Software Engineer III - GCP, CDN, Service Mesh, Envoy Proxy (Cloud Routing Team) - Groupon

Grow as an engineer by building tools that grow local businesses

You became an engineer because you believed in technology’s ability to make a difference in the world. So why would you spend your days building things that don’t matter?

Groupon is an experiences marketplace that brings people more ways to get the most out of their city or wherever they may be. By enabling real-time mobile commerce across local businesses, live events and travel destinations, Groupon helps people find and discover experiences––big and small, new and familiar––that make for a full, fun and rewarding life. Groupon helps local businesses grow and strengthen customer relationships––resulting in strong, vibrant communities. Even with thousands of employees spread across multiple continents, we still maintain a culture that inspires innovation, rewards risk-taking and celebrates success.

As a Cloud Engineer on our Cloud Platform team, you will grow your career by working for an international, multicultural company with thousands of employees that runs on a Service-oriented architecture (SOA) with 300 microservices and millions of concurrent clients. You should be fascinated about performance, capacity, and stability, and be passionate about the quality of code and test coverage, as those things are critical to the success of our system.

In this role, you will help drive innovation within the team bringing your knowledge and expertise in routing and CDNs. You will contribute to critically assessing and improving current designs and configurations, ensuring that the company’s cloud infrastructure remains at the cutting edge of technology and best practices. You will work with application owners to understand their needs and define requirements for their operation in the cloud platform. This role involves working with cutting-edge technology and solving challenging technical problems. The platform capabilities we are building will be used by every engineering team at Groupon, and this is your chance to influence how microservices are developed and deployed on a company-wide scale.

We're a "best of both worlds" kind of company. We're big enough to have resources and scale, but small enough that a single person has a surprising amount of autonomy and can make a meaningful impact. We're curious, fun, a little intense, and kind of obsessed with helping local businesses thrive.
